Meteoroid/Meteor/Meteorite Facts

1. A meteoroid is a small rock or particle of debris in our Solar System. They range
in size from dust to around 33 feet in diameter (larger objects are usually referred
to as asteroids).
2. A meteoroid that burns up as it passes through the Earth’s atmosphere is known
as a meteor. If you’ve ever looked up at the sky at night and seen a streak of light
or ‘shooting star.’ what you are actually seeing is a meteor.
3. A meteoroid that survives falling through the Earth’s atmosphere and colliding
with the Earth’s surface is known as a meteorite.
4. The Earth’s atmosphere experiences millions of meteors every day.
5. Meteors are best seen during the night.
6. When many meteors occur in a close time frame in the same part of the sky, it is
called a meteor shower.
7. Around 500 meteorites reach the Earth’s surface every year but of those, only
around five ever make it to scientists for study.
8. When a meteor produces enough light to cast a shadow (at night) on the Earth it
is called a fireball. It is also easily seen during daytime.
9. Many meteorites are found in Antarctica.
10.
A meteor is a tiny particle from outer space that produces light as it enters
the Earth's atmosphere.
11.
The largest meteors are sometimes broken bits of asteroids.
12.
On any night, any location, a few meteors can be seen each hour.
13.
When a meteoroid enters the atmosphere it creates a meteor, and what’s
left of the meteor, if anything, falls to the Earth and is called a meteorite.
